I'm going to be using an old 2ds with the r4 gold pro 2020 flashcart, official kernel(the reason why ill be using the official kernel is because they always update the firmware, and it runs better than ysmenu)
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
